(1) Note. The rubber, resin, or organic -C(=O)O- compound normally, but not necessarily, serves a binding function.

(2) Note. The term "resin" is intended to include all material identified as unspecified resin, all natural resins, and synthetic resins not prepared by polymerization or

copolymerization of a specified monomer or of specified monomers.

(3) Note. An organic -C(=O)O- compound is one in which the carbon of the -C(=O)O- group is, or is attached directly or indirectly by nonionic bonding to, the carbon of an organic compound.
